Description

[Technical Field]

[0001] The present invention relates to sensing systems and lighting systems. [Background technology]

[0002] Conventionally, there is a lighting system that comprises multiple human body detection units that detect the presence or absence of a human body, one or more lighting fixtures, and a control unit that controls the lighting of the lamps of the lighting fixtures based on the detection signals of the human body detection units (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-162658 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional lighting systems, the control unit turns off the lamps of the lighting fixtures when a person is no longer detected or after a certain period of time has passed since the detection of a person was stopped. However, in conventional lighting systems, in order to centrally receive detection signals from multiple human body detectors and control the lighting fixtures collectively, a separate control device that is not directly related to human body detection, such as a gateway or receiver, is required. This creates problems such as complicated installation of lighting devices and high costs for the lighting devices, particularly in buildings that require a large number of lighting devices, such as office buildings.

[0005] On the other hand, there are also lighting systems in which multiple motion sensors with human detection units each have a control unit. In such lighting systems, multiple motion sensors individually send signals to common lighting fixtures: one to turn on the light when it detects a person, and another to turn off the light after a certain period of time. Therefore, when multiple motion sensors simultaneously send on and off signals, multiple control signals fly around within the network, which can cause the lighting system to malfunction.

[0006] Specifically, for example, if a first motion sensor detects a person and turns on a lighting fixture, and then a second motion sensor detects a person and turns on the light, the first motion sensor may send a signal to turn off the light, causing the lighting fixture to turn off even though a user is still near the second motion sensor.

[0007] The present invention has been made in view of the above-mentioned problems, and has an object to provide a sensing system and a lighting system that can control lighting fixtures accurately at low cost. [Means for solving the problem]

[0009] In the sensing system of the present invention, each of the multiple human presence sensors may be configured to be switchable between a parent unit mode in which it functions as a parent unit side human presence sensor and a child unit mode in which it functions as a child unit side human presence sensor.

[0010] In the sensing system of the present invention, the parent unit side human presence sensor may be provided with a memory unit that stores lighting control information for the one or more lighting devices, and the lighting control signal upon detection may include the lighting control information.

[0011] In the sensing system of the present invention, the parent unit side human presence sensor may be configured to transmit an elapsed time lighting control signal, which is a control signal for the lighting device, when a predetermined time has elapsed after transmitting the detection time lighting control signal.

[0012] In the sensing system according to the present invention, the detection time illumination control signal may be a signal that increases the brightness of the lighting device, and the elapsed time illumination control signal may be a signal that decreases the brightness of the lighting device.

[0013] In the sensing system according to the present invention, the detection illumination control signal may be a signal that causes the lighting device to turn on in a first color, and the elapsed time illumination control signal may be a signal that causes the lighting device to turn on and off in a second color.

[0015] In the lighting system according to the present invention, the plurality of motion sensors and the one or more lighting fixtures may form a mesh network.

[0016] In the lighting system of the present invention, at least one of the parent unit side motion sensor, the child unit side motion sensor, and the lighting fixture may be configured to issue an alert to the user when multiple parent unit side motion sensors are detected on the mesh network.

[0017] In the lighting system of the present invention, a setting terminal is provided that can set lighting control information for the one or more lighting fixtures, the parent unit side human presence sensor is provided with a memory unit that stores the lighting control information set by the setting terminal, and the lighting control signal upon detection may include the lighting control information.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The best mode for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. Furthermore, the drawings are schematic diagrams in which emphasis, omission, and proportion adjustments have been made as appropriate to illustrate the present invention, and may differ from the actual shapes, positional relationships, and proportions.

[0021] [Configuration of the lighting system according to this embodiment] First, a lighting system 1 according to this embodiment will be outlined with reference to Figures 1 and 2. As shown in Figures 1 and 2, the lighting system 1 according to this embodiment includes a sensing system 2 and one or more lighting fixtures 100. The sensing system 2 includes a plurality of motion sensors 10 capable of detecting a human body. The lighting system 1 also includes a setting terminal 200. The plurality of motion sensors 10 and the one or more lighting fixtures 100 form a mesh network NW.

[0022] The plurality of human presence sensors 10 include a parent-side human presence sensor 10a that functions as a parent device and a child-side human presence sensor 10b that functions as a child device, and the parent-side human presence sensor 10a and the child-side human presence sensor 10b are configured to be capable of direct or indirect wireless communication. In this embodiment, when there is no need to distinguish between the parent-side human presence sensor 10a and the child-side human presence sensor 10b, they are simply referred to as human presence sensors 10.

[0023] In this embodiment, the plurality of motion sensors 10 constituting one mesh network NW includes one master-side motion sensor 10a and one or more slave-side motion sensors 10b. In other words, it is not possible to connect multiple master-side motion sensors 10a to one mesh network NW.

[0024] Therefore, at least one of the parent device side motion sensor 10a, the child device side motion sensor 10b, and the lighting fixture 100 is configured to issue a warning to the user when it detects multiple parent device side motion sensors 10a on the mesh network NW. Specific methods for issuing the warning will be described later in the configurations of the motion sensors 10 and the lighting fixtures 100.

[0025] The lighting system 1 according to this embodiment can be installed at any position inside or outside a building. Specifically, the lighting system 1 can be installed on each floor of a building where people come and go, such as an ordinary house, an office building, a housing complex such as a condominium or apartment, a care and welfare facility such as a nursing home, a senior citizen housing complex with services, or a group home, or a public facility such as a hospital or a school.

[0026] [Configuration of the lighting fixture according to this embodiment] As shown in Fig. 3, lighting fixture 100 includes illumination unit 120 having a light-emitting unit, communication unit 140, control unit 160, and storage unit 180. In this embodiment, lighting fixture 100 is a base light as shown in Fig. 2, but is not limited to this and may be a downlight, a spotlight, or the like.

[0027] The lighting fixture 100 is configured so as to be mountable to a wall or ceiling of a building using a mounting bracket. In this embodiment, the lighting fixture 100 is mounted on a lighting duct rail (not shown), but is not limited to this.

[0028] The lighting unit 120 has a dimming function and a color adjustment function, and is configured to be able to change the brightness, color temperature, and emitted color of the light-emitting unit. The brightness, color temperature, and emitted color of the light-emitting unit are controlled by a lighting control unit 162 (described later) of the control unit 160. Note that the lighting unit 120 can employ a known configuration, and therefore a detailed description thereof will be omitted.

[0029] The communication unit 140 is configured to be able to communicate with the communication units 140 of the other lighting fixtures 100, the communication unit 14 (described later) of the human presence sensor 10, and the communication unit (described later) of the setting terminal 200. Specifically, the communication unit 140 is configured to be able to receive signals transmitted from the communication unit 14 of the human presence sensor 10, the communication unit of the setting terminal 200, and the communication unit 140 of the other lighting fixtures 100, and is configured to be able to transmit the received signals to the communication unit 140 of the other lighting fixtures 100 and the communication unit 14 of the human presence sensor 10.

[0030] By including such a communication unit 140, the lighting fixture 100 can build a mesh network NW together with the motion sensor 10 as shown in FIG. 1, and multiple paths can be used for communication.

[0031] In addition, when the communication unit 140 detects multiple parent unit side human sensors 10a on the mesh network NW, the communication unit 140 may cause the lighting control unit 162 of the control unit 160 to flash the light emitting unit of the lighting unit 120 to alert the user.

[0032] 3, the control unit 160 includes a control signal receiving unit 161 and a lighting control unit 162. The control signal receiving unit 161 is configured to directly or indirectly receive a detection-time lighting control signal (to be described later) and a lapse-time lighting control signal (to be described later) transmitted by a control signal transmitting unit 36 ​​(to be described later) of the parent-side human presence sensor 10a via the communication unit 140. In this embodiment, receiving indirectly means receiving via the child-side human presence sensor 10b that constitutes the mesh network NW, another lighting fixture 100, etc.

[0033] The illumination control unit 162 includes a lighting control unit 163, a dimming control unit 164, and a color adjustment control unit 165. The lighting control unit 163 is configured to be able to control the turning on and off of the light-emitting unit of the illumination unit 120. The dimming control unit 164 is configured to be able to control the brightness of the light-emitting unit. The color adjustment control unit 165 is configured to be able to control the color temperature and emitted color of the light-emitting unit. In the illumination control unit 162, the lighting control unit 163, the dimming control unit 164, and the color adjustment control unit 165 control the light-emitting unit based on lighting control information 62, which will be described later, included in the detection illumination control signal and the elapsed illumination control signal received by the control signal receiving unit 161.

[0034] For example, when the motion sensor 10 detects a human body while the light-emitting unit of the illumination unit 120 is turned off, the lighting control unit 163 turns on the light-emitting unit. Furthermore, when the motion sensor 10 detects a human body while the light-emitting unit is dimly lit, the dimming control unit 164 increases the brightness of the light-emitting unit. Furthermore, when the motion sensor 10 detects a human body, the color adjustment control unit 165 may change at least one of the color temperature and the emitted color of the light-emitting unit.

[0035] [Configuration of the Human Sensor According to the Present Embodiment] As shown in Fig. 4, the human presence sensor 10 includes a human body detection unit 12, a communication unit 14, and a control unit 20. The human presence sensor 10 also includes an indicator 16, an alarm light source 17, an illuminance sensor 18, a memory unit 60, a selector switch 70, and a communication switch 80. The human presence sensor 10 is configured so as to be mountable to a wall or ceiling of a building using a mounting bracket. In this embodiment, the human presence sensor 10 includes a housing 11, and the housing 11 is mounted on a lighting duct rail. However, the present invention is not limited to this.

[0036] As shown in Figures 2 and 5, the human body detection unit 12 is provided at the bottom of the housing 11 and is configured to be able to detect the approach of a human body. In this embodiment, the human body detection unit 12 is an infrared sensor (heat ray sensor) and is covered with a dome-shaped cover lens 13. However, the human body detection unit 12 is not limited to this, and various arbitrary configurations can be adopted as long as it is configured to be able to detect a human body. For example, the human body detection unit 12 may include an ultrasonic sensor, a microwave sensor, a photoelectric sensor, a pressure sensor, a sound sensor, etc.

[0037] In addition, the human body detection unit 12 may be configured to detect human bodies based on images captured by a camera, opening and closing of doors, locking and unlocking of doors, reading of entry and exit management cards using a card reader, operation of an intercom, etc.

[0038] The human body detection unit 12 measures the surroundings of the human sensor 10. The measurement value of the human body detection unit 12 is transmitted to the control unit 20.

[0039] Communication unit 14 is configured to be able to communicate with communication unit 14 of other presence sensors 10, communication unit 140 of lighting device 100, and communication unit 140 of setting terminal 200. Specifically, communication unit 14 is configured to be able to receive signals transmitted from communication unit 14 of other presence sensors 10, communication unit 140 of setting terminal 200, and communication unit 140 of lighting device 100, and is configured to be able to transmit the received signals to communication unit 14 of other presence sensors 10 and communication unit 140 of lighting device 100.

[0040] By providing such a communication unit 14, the motion sensor 10 can build a mesh network NW together with the lighting fixtures 100, as shown in Fig. 1, and multiple paths can be used for communication. Even if multiple motion sensors 10 and one or more lighting fixtures 100 are outside the communication range of each other, communication is possible by using multiple connections as long as the motion sensors 10 and lighting fixtures 100 belong to the same network.

[0041] Furthermore, when the communication unit 14 detects a plurality of parent device side human sensors 10a on the mesh network NW, the communication unit 14 may flash the indicator 16 or the notification light source 17 to notify the user of a warning.

[0042] The indicator 16 includes an LED light source and is configured to indicate the setting of the human presence sensor 10 depending on its lighting state. The indicator 16 is provided on the bottom of the housing 11, as shown in FIG. 5 . In this embodiment, the indicator 16 includes five LED light sources. However, this is not limited to this, and any number of LEDs may be used. In this embodiment, the notification light source 17 includes a red LED light source and a green LED light source and is disposed inside the cover lens 13. However, this is not limited to this, and any number and color of the light sources included in the notification light source 17 may be used. The notification light source 17 is configured to light up when a human body is detected or when a detection signal is received from another human presence sensor 10. This configuration allows visual confirmation of which human presence sensor 10 has detected a human body. Furthermore, the notification light source 17 is configured so that a green LED light source lights up when the human presence sensor 10 is in a master mode (described below), and a red LED light source lights up when the human presence sensor 10 is in a slave mode (described below). With this configuration, it is also possible to visually determine whether the human presence sensor 10 is the parent unit side human presence sensor 10a or the child unit side human presence sensor 10b by the lighting color of the notification light source 17.

[0043] Illuminance sensor 18 is disposed inside cover lens 13 and is configured to be able to detect the brightness of the surroundings of motion sensor 10. By including illuminance sensor 18, motion sensor 10 according to this embodiment can switch the lighting state of lighting device 100 in accordance with the brightness of the surroundings detected by human body detection unit 12 and illuminance sensor 18. Whether or not illuminance sensor 18 is to function can be set by a sensed illuminance selector switch 77 of selector switch 70 (described later) or by setting terminal 200.

[0044] As shown in Fig. 4, the control unit 20 includes a parent mode control unit 30 and a child mode control unit 40. The human presence sensor 10 equipped with such a control unit 20 is configured to be switchable between a parent mode in which it functions as a parent-side human presence sensor 10a and a child mode in which it functions as a child-side human presence sensor 10b. As shown in Fig. 6, the human presence sensor 10 is configured to be switchable between the parent mode and the child mode by a mode selector switch 72 of a selector switch 70, which will be described later.

[0045] 4, the parent mode control unit 30 includes a detection signal transmission unit 32, a control signal transmission unit 36, and a lighting control information setting unit 38. The detection signal transmission unit 32 is configured to transmit a detection signal when the human body detection unit 12 detects a human body.

[0046] Specifically, the detection signal transmission unit 32 is configured to perform a detection determination process to determine whether the human body detection unit 12 has detected a human body, and a detection signal transmission process to transmit a detection signal when it is determined that a human body has been detected.

[0047] Furthermore, in this embodiment, when the illuminance sensor 18 is functioning, the human body detection unit 12 is configured to execute a detection signal transmission process when it is determined that the human body has detected a human body and that the illuminance measurement value of the illuminance sensor 18 is lower than a predetermined set value. However, this is not limiting.

[0048] Furthermore, the detection signal transmitting section 32 is configured to transmit the detection signal again when it is determined that a human body has been detected again before the lighting time, which will be described later, has elapsed.

[0049] The control signal transmitter 36 is configured to transmit a detection-time illumination control signal, which is a control signal for the lighting device 100, when a human body is detected or a detection signal is received. Specifically, the control signal transmitter 36 is configured to execute a detection-time control signal transmission process to transmit a detection-time illumination control signal when the detection signal transmitter 32 determines that a human body has been detected in the detection determination process or when the control signal transmitter 36 receives a detection signal directly or indirectly from the slave-side motion sensor 10b. In this embodiment, receiving the detection signal indirectly means receiving the detection signal via a lighting device 100 that constitutes the mesh network NW, another slave-side motion sensor 10b different from the slave-side motion sensor 10b that transmitted the detection signal, or the like.

[0050] The detection illumination control signal includes lighting control information 62 (in this embodiment, detection illumination control information 62a). The detection illumination control signal is, for example, a signal that increases the brightness of lighting device 100. However, this is not limited to this. In this embodiment, a signal that increases brightness is a signal that switches the light-emitting elements of lighting unit 120 of lighting device 100 from an off state to on, or a signal that increases the brightness of a light-emitting element that was on before human body detection.

[0051] That is, the detection time lighting control information 62a included in the detection time lighting control signal is, for example, lighting control information for lighting the light emitting unit of the lighting unit 120 or dimming control information for dimming the light emitting unit to a brighter level, but is not limited to this.

[0052] When detection-time lighting control information 62a included in the detection-time lighting control signal is dimming control information for dimming the light-emitting unit, lighting system 1 turns on lighting device 100 at, for example, 10% illumination before detecting a human body, as shown in Fig. 7a. Then, in lighting system 1, after human presence sensor 10 detects a human body and master-side human presence sensor 10a sends a detection-time lighting control signal to lighting device 100, lighting device 100 turns on at, for example, 90% illumination, as shown in Fig. 7b.

[0053] In this embodiment, the detection illumination control signal is a signal that turns on the light-emitting unit at the time of shipment, and can be changed to a signal that makes the light-emitting unit brighter by the user operating the setting terminal 200. However, this is not limiting. For example, the detection illumination control signal may be changeable by the user operating the selector switch 70. Specifically, the detection illumination control signal may be changed by the user operating the selector switch 70. In particular, the detection illumination control signal may be changed by the user operating the selector switch 70 to select any one of the plurality of pieces of detection illumination control information 62a from among the plurality of pieces of lighting control information 62 stored in the lighting control information master 64 of the storage unit 60. Furthermore, the detection illumination control signal may be changed by operating the selector switch 70 to light up the indicator 16 or the notification light source 17 in accordance with the selection of the lighting control information 62 that can be selected as the detection illumination control information 62a.

[0054] The detection illumination control signal may be a signal that instantly changes the brightness to a predetermined brightness, or may be a signal that changes the brightness continuously or stepwise to the predetermined brightness.

[0055] Furthermore, control signal transmitter 36 is configured to transmit an elapsed time illumination control signal, which is a control signal for lighting device 100, when a predetermined time (in this embodiment, the lighting time) has elapsed after transmitting the detection time illumination control signal. Specifically, control signal transmitter 36 is configured to execute a time elapse determination process that determines whether or not the predetermined lighting time has elapsed after the detection time control signal transmission process, and an elapsed time control signal transmission process that transmits an elapsed time illumination control signal when it is determined that the lighting time has elapsed.

[0056] In this embodiment, a plurality of selectable lighting times are set, and the lighting time can be switched by the user using the lighting time changeover switch 76 described below. However, the present invention is not limited to this, and the lighting time does not have to be switchable by the user. Alternatively, the lighting time may be set to any time by the user using the setting terminal 200.

[0057] Furthermore, control signal transmitter 36 is configured to transmit the upon-detection illumination control signal again if it detects a human body again or receives a detection signal again before the lighting time has elapsed. For example, as shown in FIG. 8 , if two motion sensors 10 installed along a user's movement path detect a human body in succession, control signal transmitter 36 transmits the upon-detection illumination control signal twice to lighting device 100. Furthermore, if two motion sensors 10 each detect a different human body, control signal transmitter 36 transmits the upon-detection illumination control signal twice to lighting device 100. Furthermore, if a user moves back and forth under motion sensor 10 and the same motion sensor 10 detects a human body twice, control signal transmitter 36 transmits the upon-detection illumination control signal twice to lighting device 100.

[0058] The elapsed time illumination control signal includes lighting control information 62 (in this embodiment, elapsed time illumination control information 62b). The elapsed time illumination control signal is, for example, a signal to reduce the brightness of lighting device 100. However, this is not limited to this. In this embodiment, a signal to reduce brightness is a signal to turn off the light-emitting element of lighting unit 120 of lighting device 100 from a lit state, or a signal to dim the brightness of a light-emitting element that is lit after a human body is detected.

[0059] That is, the elapsed time lighting control information 62b included in the elapsed time lighting control signal is, for example, information on extinguishing control to turn off the light emitting unit of the lighting unit 120 or information on dimming control to dim the light emitting unit, but is not limited to this.

[0060] When the elapsed time lighting control information 62b included in the elapsed time lighting control signal is dimming control information for dimming the light-emitting unit, after a predetermined lighting time has elapsed since the human presence sensor 10 last detected a human body and the elapsed time lighting control signal is sent from the parent unit human presence sensor 10a to the lighting device 100, the lighting device 100 turns on, for example, at 10% illumination, as shown in Figure 7c.

[0061] In this embodiment, the elapsed time illumination control signal is a signal for turning off the light-emitting unit at the time of shipment, and can be changed to a signal for dimming the brightness of the light-emitting unit by the user operating the setting terminal 200. However, this is not limiting. For example, the elapsed time illumination control signal may be changed by the user operating the selector switch 70. Specifically, the elapsed time illumination control signal may be configured to be selectable by the user operating the selector switch 70 from among the plurality of pieces of lighting control information 62 stored in the lighting control information master 64 of the storage unit 60. Furthermore, the indicator 16 or the notification light source 17 may be configured to light up in accordance with the selection of the lighting control information 62 selectable as the elapsed time illumination control information 62b when the selector switch 70 is operated.

[0062] The elapsed time illumination control signal may be a signal that instantly changes the brightness to a predetermined brightness or to an off state, or may be a signal that changes the brightness continuously or stepwise to the predetermined brightness or to the off state.

[0063] Furthermore, the detection illumination control signal and the elapsed illumination control signal are not limited to signals that change the brightness of lighting device 100. For example, the detection illumination control signal may be a signal that causes lighting device 100 to light up in a first color, and the elapsed illumination control signal may be a signal that causes lighting device 100 to light up in a second color. Specifically, when a human body is detected, control signal transmitter 36 may cause lighting device 100 to light up in a warning color such as red or yellow to alert the user or in a warm color to welcome the user, and after the lighting time has elapsed, may cause lighting device 100 to light up in a normal color such as neutral white or daylight.

[0064] In addition, when the detection illumination control signal and the elapsed illumination control signal are signals that change the light emission color of the light-emitting unit of the illumination unit 120 of the lighting device 100, the lighting control unit 162 of the control unit 160 of the lighting device 100 has the color adjustment control unit 165 control the light emission color of the light-emitting unit.

[0065] Lighting control information setting unit 38 is configured to be able to change detection-time lighting control information 62a and elapsed-time lighting control information 62b. Specifically, when the user changes the settings for control of lighting device 100 at the time of detection or the time of elapsed time via selector switch 70 or setting terminal 200, lighting control information setting unit 38 reads lighting control information 62 from lighting control information master 64 (described later) and changes at least one of detection-time lighting control information 62a and elapsed-time lighting control information 62b.

[0066] 4, the slave mode control unit 40 includes a detection signal transmitting unit 42 and a detection signal receiving unit 44. The detection signal transmitting unit 42 is configured to transmit a detection signal when the human body detecting unit 12 detects a human body.

[0067] Specifically, the detection signal transmission unit 42 is configured to perform a detection determination process to determine whether the human body detection unit 12 has detected a human body, and a detection signal transmission process to transmit a detection signal when it is determined that a human body has been detected.

[0068] Furthermore, in this embodiment, when the illuminance sensor 18 is functioning, the detection signal transmission unit 42 is configured to execute a detection signal transmission process when it determines that the human body detection unit 12 has detected a human body and that the illuminance measurement value of the illuminance sensor 18 is lower than a predetermined set value. However, this is not limiting.

[0069] After transmitting the detection signal, the slave mode control unit 40 enters a detection standby state. If the detection signal transmission unit 42 determines that a human body has been detected after transmitting the detection signal, the detection signal transmission unit 42 executes the detection signal transmission process again.

[0070] The detection signal receiver 44 receives a detection signal directly or indirectly from the master side motion sensor 10a or another slave side motion sensor 10b. After receiving the detection signal, the slave mode controller 40 enters a detection standby state. That is, when a detection signal is received from the master side motion sensor 10a or another slave side motion sensor 10b, the slave side motion sensor 10b does not transmit a signal related to the control of the lighting device 100. Furthermore, if the detection signal transmitter 42 determines that a human body has been detected after receiving the detection signal, the detection signal transmitter 42 executes a detection signal transmission process.

[0071] The storage unit 60 stores lighting control information 62 for one or more lighting fixtures 100, a lighting control information master 64, and a sensing system control program 68. In this embodiment, the storage unit 60 stores, as the lighting control information 62, detection-time lighting control information 62a included in the detection-time lighting control signal and elapsed-time lighting control information 62b included in the elapsed-time lighting control signal.

[0072] In this embodiment, detection time lighting control information 62a included in the detection time lighting control signal at the time of shipment of human presence sensor 10 is lighting control information for turning on the light-emitting unit of lighting unit 120 of lighting device 100, and elapsed time lighting control information 62b included in the elapsed time lighting control signal at the time of shipment of human presence sensor 10 is light-off control information for turning off the light-emitting unit. However, detection time lighting control information 62a and elapsed time lighting control information 62b at the time of shipment are not limited to this.

[0073] The detection time lighting control information 62a included in the detection time lighting control signal and the elapsed time lighting control information 62b included in the elapsed time lighting control signal are set by changing the setting via a changeover switch 70, which will be described later, so that lighting control information 62 different from that at the time of shipment is read and set from the lighting control information master 64. Furthermore, the detection time lighting control information 62a included in the detection time lighting control signal and the elapsed time lighting control information 62b included in the elapsed time lighting control signal may be lighting control information 62 set by the setting terminal 200, as will be described later.

[0074] The lighting control information master 64 is a list of lighting control information 62 that the user can set in the detection lighting control information 62a and the elapsed time lighting control information 62b. The lighting control information 62 included in the lighting control information master 64 includes information on lighting control for turning on the light-emitting unit of the lighting unit 120 of the lighting device 100, turning off control for turning off the light-emitting unit, dimming control for dimming the light-emitting unit to a brighter level, and dimming control for dimming the light-emitting unit to a darker level.

[0075] Specifically, the lighting control information master 64 includes, for example, lighting control information 62 selectable as detection-time lighting control information 62a, lighting control information for lighting the light-emitting unit of the lighting unit 120 of the lighting device 100 at 100% lighting state, and four types of dimming control information for dimming the light-emitting unit to 60%, 70%, 80%, and 90% lighting states. However, this is not limiting. The lighting control information master 64 may also include information on multiple color adjustment controls.

[0076] Furthermore, lighting control information master 64 includes, for example, lighting control information 62 selectable as elapsed time lighting control information 62b, information on extinguishing control for extinguishing the light-emitting unit of lighting unit 120 of lighting device 100, and information on four types of dimming control for dimming the light-emitting unit to 10%, 20%, 30%, and 40% lighting states. However, this is not limited to this. Furthermore, lighting control information master 64 may include information on multiple color adjustment controls. Furthermore, lighting control information master 64 may include lighting control information 62 set by setting terminal 200.

[0077] The sensing system control program 68 causes the slave-side human sensor 10b of the sensing system 2 to transmit a detection signal when it detects a human body. The sensing system control program 68 also causes the master-side human sensor 10a to transmit a detection illumination control signal when it detects a human body or when it receives a detection signal directly or indirectly from the slave-side human sensor 10b.

[0078] 4, the selector switch 70 includes a mode selector switch 72, a detection signal transmitting switch 74, an elapsed time signal transmitting switch 75, a lighting time selector switch 76, a sensed illuminance selector switch 77, and a sensor operation switch 78. The mode selector switch 72, the detection signal transmitting switch 74, the elapsed time signal transmitting switch 75, the lighting time selector switch 76, the sensed illuminance selector switch 77, and the sensor operation switch 78 are provided on the bottom of the housing 11, as shown in FIG.

[0079] In this embodiment, the mode changeover switch 72 is a slide switch that can be switched between two stages, left and right. In this embodiment, the human presence sensor 10 functions as a parent unit human presence sensor 10a when the mode changeover switch 72 is on the left side, and functions as a child unit human presence sensor 10b when the mode changeover switch 72 is on the right side, as shown in FIG.

[0080] The configuration of the mode selector switch 72 is not limited to this, and the relationship between each mode and the position of the slide switch may be reversed. Also, the mode selector switch 72 may be a rocker switch, a toggle switch, a tactile switch (push button switch), or a tactile switch. When the mode selector switch 72 is a slide switch, a rocker switch, or a toggle switch, it has the advantage that the user can easily distinguish whether the mode is parent mode or child mode.

[0081] The detection signal transmission switch 74 is a tactile switch configured to, when pressed, forcibly transmit a detection illumination control signal to the control signal transmission unit 36 ​​of the parent mode control unit 30 of the parent-side human presence sensor 10a on the network. Note that, after the detection signal transmission switch 74 is operated, the human body detection functions of the multiple human presence sensors 10 are stopped. Furthermore, after the detection signal transmission switch 74 is operated, the control signal transmission unit 36 ​​is configured not to automatically transmit an elapsed illumination control signal even if a predetermined time has elapsed since transmitting the detection illumination control signal. Therefore, the light-emitting unit of the illumination unit 120 of the lighting fixture 100 remains lit based on the lighting control information 62 included in the detection illumination control signal until the elapsed signal transmission switch 75 or the sensor operation switch 78 is operated. This configuration has the advantage that, for example, when it is desired to keep the light-emitting unit of the illumination unit 120 lit for a long period of time, the light-emitting unit can be kept lit without being automatically turned off by operating the detection signal transmission switch 74.

[0082] The elapsed time signal transmitting switch 75 is a tactile switch that, when pressed, is configured to forcibly transmit an elapsed time illumination control signal to the control signal transmitting unit 36 ​​of the parent mode control unit 30 of the parent side human presence sensor 10a on the network. After the elapsed time signal transmitting switch 75 is operated, the multiple human presence sensors 10 are configured to stop their human body detection functions.

[0083] The lighting time selector switch 76 is a tactile switch and is configured to be able to change the lighting time. The selectable lighting times are, for example, five levels: "10 seconds," "30 seconds," "1 minute," "3 minutes," and "10 minutes." However, the lighting times are not limited to these, and various other lighting times can be used. The user selects any lighting time from the multiple lighting times that are set by repeatedly pressing the lighting time selector switch 76. When the lighting time selector switch 76 is pressed, the indicator 16 is configured to light up according to the five lighting times.

[0084] The sensed illuminance changeover switch 77 is a tactile switch configured to be able to change the set value of the illuminance (sensible illuminance) used by the detection signal transmitters 32, 42 of the master mode controller 30 and the slave mode controller 40 when determining whether the illuminance around the human sensor 10 has decreased. The sensed illuminance that can be selected is set to five levels, for example, "5 lx," "15 lx," "25 lx," "35 lx," and "off." However, the sensed illuminance is not limited to these levels, and various other illuminance levels can be used.

[0085] Also, by selecting "Off," the function of the illuminance sensor 18 can be stopped. In other words, the human presence sensor 10 determines whether or not to execute the detection signal transmission process based solely on the detection result of the human body detection unit 12, regardless of the ambient brightness. The user selects any of the multiple detected illuminances that have been set by repeatedly pressing the detected illuminance selector switch 77. When the detected illuminance selector switch 77 is pressed, the indicator 16 is configured to light up according to one of five lighting durations.

[0086] The sensor operation switch 78 is a tactile switch that, when pressed, operates the detection signal transmission switch 74 or the elapsed time signal transmission switch 75 to resume human body detection in the multiple human body sensors 10 whose human body detection function has been stopped. That is, the sensor operation switch 78 is effective whether the human body sensors 10 are in master mode or slave mode. Operating the sensor operation switch 78 of either the master-side human body sensor 10a or the slave-side human body sensor 10b also resumes human body detection in the other human body sensors 10. In this embodiment, after operating the sensor operation switch 78, the master-side human body sensor 10a transmits an elapsed time illumination control signal. However, this is not limited to this. If the light-emitting unit of the lighting unit 120 of the lighting fixture 100 is on and the lighting state remains unchanged when the sensor operation switch 78 is pressed, the user will not know that human body detection has resumed. However, this configuration allows the user to confirm that human body detection has resumed. Specifically, by transmitting the elapsed time illumination control signal, the lighting state of the light-emitting unit changes once, and further, since the user who pressed the sensor operation switch 78 after transmitting the detection time illumination control signal is detected by the human presence sensor 10 having the sensor operation switch 78, the detection time illumination control signal is transmitted from the parent unit side human presence sensor 10a, and the lighting state of the light-emitting unit changes again. This has the advantage that the user can visually know that human body detection has resumed.

[0087] The communication switch 80 is a switch used when connecting the lighting fixture 100, the setting terminal 200, and other motion sensors 10.

[0088] The setting terminal 200 is, for example, a tablet terminal or a remote control, and is configured to be able to set the lighting control information 62. Specifically, the setting terminal 200 allows a user to set the detection-time lighting control information 62a and the elapsed time lighting control information 62b, and transmits the set detection-time lighting control information 62a and the elapsed time lighting control information 62b. The detection-time lighting control information 62a and the elapsed time lighting control information 62b set by the setting terminal 200 may directly overwrite the detection-time lighting control information 62a and the elapsed time lighting control information 62b stored in the memory unit 60 of the parent unit-side human presence sensor 10a, or may be newly added to the lighting control information master 64 of the memory unit 60. The setting terminal 200 may also be configured to allow a user to set the lighting duration and the sensed illuminance.

[0089] Furthermore, setting terminal 200 includes a communication unit (not shown). The communication unit of setting terminal 200 is configured to be able to communicate with communication unit 14 of motion sensor 10 and communication unit 140 of lighting fixture 100. Specifically, the communication unit of setting terminal 200 is configured to be able to transmit a setting signal including lighting control information 62. The setting signal may include lighting time and sensed illuminance.

[0090] [Description of lighting control method according to this embodiment] Next, an example of a lighting control method for the lighting system 1 according to this embodiment will be described with reference to Fig. 9. Note that in this embodiment, the illuminance sensor 18 is described as not functioning, but this is not limiting. Also, in this embodiment, Fig. 9 shows the human presence sensor 10 as terminating its operation after executing a series of processes for the sake of convenience in describing the flowchart, but this is not limiting, and the human presence sensor 10 enters a detection standby state.

[0091] First, the detection signal transmitting unit 32 of the parent mode control unit 30 of the control unit 20 of the parent side human sensor 10a determines whether the human body detecting unit 12 of the parent side human sensor 10a has detected a human body (S1 in FIG. 9: detection determining step). If the detection signal transmitting unit 32 determines that a human body has been detected (YES in S1 in FIG. 9), it transmits a detection signal (S2 in FIG. 9: detection signal transmitting step).

[0092] Meanwhile, the detection signal transmitting unit 42 of the slave mode control unit 40 of the control unit 20 of the slave side human sensor 10b also determines whether the human body detecting unit 12 of the slave side human sensor 10b has detected a human body, similar to the master side (S20 in FIG. 9: detection determining step). When the detection signal transmitting unit 42 determines that a human body has been detected (YES in S20 in FIG. 9), it transmits a detection signal (S21 in FIG. 9: detection signal transmitting step).

[0093] Furthermore, regardless of whether the detection signal transmitter 42 has determined that a human body has been detected, when the detection signal transmitter 32 of the parent mode controller 30 of the parent side human sensor 10a transmits a detection signal, the detection signal receiver 44 of the child mode controller 40 receives the detection signal from the parent side human sensor 10a (child side detection signal receiving step). When the detection signal receiver 44 receives the detection signal, the child side human sensor 10b enters a detection standby state.

[0094] Also, when the detection signal receiving unit 44 of the slave mode control unit 40 does not receive a detection signal, the slave side human presence sensor 10b is in a detection standby state.

[0095] Thereafter, when detection signal transmission unit 42 of slave mode control unit 40 of slave-side motion sensor 10b transmits a detection signal, control signal transmission unit 36 ​​of master-side motion sensor 10a receives the detection signal from slave-side motion sensor 10b (S3 in FIG. 9: master-side detection signal reception step). After detection signal transmission unit 32 transmits the detection signal, or when control signal transmission unit 36 ​​receives a detection signal (YES in S3 in FIG. 9), control signal transmission unit 36 ​​reads detection-time lighting control information 62a from storage unit 60 and transmits a detection-time illumination control signal including detection-time lighting control information 62a to one or more lighting devices 100 (S7 in FIG. 9: detection-time control signal transmission step).

[0096] Specifically, if the detection time illumination control information 62a has been changed from the information at the time of shipment (YES in S4 of FIG. 9), the control signal transmitter 36 of the parent mode controller 30 reads the changed detection time illumination control information 62a (S5 of FIG. 9), and transmits a detection time illumination control signal including the changed detection time illumination control information 62a. Also, if the detection time illumination control information 62a has not been changed from the information at the time of shipment (NO in S4 of FIG. 9), the control signal transmitter 36 reads the detection time illumination control information 62a at the time of shipment (S6 of FIG. 9), and transmits a detection time illumination control signal including the detection time illumination control information 62a at the time of shipment.

[0097] On the other hand, if the detection signal transmission unit 32 of the parent mode control unit 30 determines that it has not detected a human body (NO at S1 in Figure 9), and the control signal transmission unit 36 ​​of the parent mode control unit 30 has not received a detection signal from the child side human sensor 10b (NO at S3 in Figure 9), the parent side human sensor 10a enters a detection standby state.

[0098] Next, the control signal receiver 161 of the control unit 160 of the lighting device 100 receives the detection-time illumination control signal (S30 in FIG. 9: detection-time illumination control signal receiving step). When the control signal receiver 161 receives the detection-time illumination control signal (YES in S30 in FIG. 9), the illumination control unit 162 of the control unit 160 controls the light-emitting unit of the illumination unit 120 based on the detection-time lighting control information 62a included in the detection-time illumination control signal received by the control signal receiver 161 (detection-time illumination control step).

[0099] Specifically, when the detection-time lighting control information 62a included in the detection-time lighting control is information other than the shipping information (YES in S31 of FIG. 9), the lighting control unit 162 causes the dimming control unit 164 to dim the light-emitting unit of the lighting unit 120 based on the detection-time lighting control information 62a, making the brightness of the light-emitting unit brighter (S32: light increase step of FIG. 9). On the other hand, when the detection-time lighting control information 62a included in the detection-time lighting control is information at the shipping time (NO in S31 of FIG. 9), the lighting control unit 162 causes the lighting control unit 163 to turn on the light-emitting unit of the lighting unit 120 (S33: lighting step of FIG. 9).

[0100] Thereafter, the control signal transmitter 36 of the master mode controller 30 of the controller 20 of the master side human sensor 10a determines whether a predetermined lighting time has elapsed after the detection control signal transmitting step (S8 in FIG. 9: time elapse determining step). If the control signal transmitter 36 determines that the lighting time has elapsed (YES in S8 in FIG. 9), it reads out the elapsed lighting control information 62b from the storage unit 60 and transmits an elapsed lighting control signal including the elapsed lighting control information 62b to one or more lighting devices 100 (S13 in FIG. 9: detection control signal transmitting step).

[0101] Specifically, if the elapsed time lighting control information 62b has been changed from the information at the time of shipment (YES in S9 of FIG. 9), the control signal transmitter 36 of the parent mode controller 30 reads the changed elapsed time lighting control information 62b (S11 of FIG. 9), and transmits an elapsed time lighting control signal including the changed elapsed time lighting control information 62b. Also, if the elapsed time lighting control information 62b has not been changed from the information at the time of shipment (NO in S9 of FIG. 9), the control signal transmitter 36 reads the elapsed time lighting control information 62b at the time of shipment (S12 of FIG. 9), and transmits an elapsed time lighting control signal including the elapsed time lighting control information 62b at the time of shipment.

[0102] Thereafter, control signal receiver 161 of controller 160 of lighting device 100 receives the elapsed time illumination control signal (S34 in FIG. 9: elapsed time illumination control signal receiving step). When control signal receiver 161 receives the elapsed time illumination control signal (YES in S40 in FIG. 9), lighting controller 162 of controller 160 controls the light-emitting unit of lighting unit 120 based on elapsed time lighting control information 62b included in the elapsed time illumination control signal received by control signal receiver 161 (elapsed time illumination control step).

[0103] Specifically, when the elapsed time lighting control information 62b included in the elapsed time lighting control is information other than that at the time of shipment (YES in S35 of FIG. 9), the dimming control unit 164 dims the light-emitting unit of the lighting unit 120 based on the elapsed time lighting control information 62b to dim the brightness of the light-emitting unit (S36: dimming step of FIG. 9). On the other hand, when the elapsed time lighting control information 62b included in the elapsed time lighting control is information at the time of shipment (NO in S35 of FIG. 9), the lighting control unit 162 causes the lighting control unit 163 to turn off the light-emitting unit of the lighting unit 120 (S37: turning off step of FIG. 9).

[0104] On the other hand, if the parent-side human sensor 10a or the child-side human sensor 10b detects a new human body (YES in S10 of FIG. 9) before the lighting time has elapsed (NO in S8 of FIG. 9), the parent-side human sensor 10a executes the previous step again without waiting for the lighting time to elapse. Specifically, if the parent-side human sensor 10a detects a human body (YES in S14 of FIG. 9), the parent-side human sensor 10a transmits a detection signal again, and if the child-side human sensor 10b detects a human body (NO in S14 of FIG. 9), the parent-side human sensor 10a reads the detection-time lighting control information 62a again and transmits the detection-time illumination control signal to the lighting device 100 again.

[0105] Furthermore, if the parent unit side human presence sensor 10a or the child unit side human presence sensor 10b does not detect a new human body (NO in S10 in FIG. 9) before the lighting time has elapsed (NO in S8 in FIG. 9), the parent unit side human presence sensor 10a waits until the lighting time has elapsed. Through the above steps, a series of lighting control methods for the lighting system 1 according to this embodiment are executed.

[0106] [Advantages of the sensing system and lighting system according to this embodiment] As described above, the sensing system 2 of this embodiment comprises a plurality of human presence sensors 10 capable of detecting a human body, and the plurality of human presence sensors 10 comprises a parent-side human presence sensor 10a that functions as a parent unit and a child-side human presence sensor 10b that functions as a child unit, the parent-side human presence sensor 10a and the child-side human presence sensor 10b being configured to be capable of direct or indirect wireless communication, the child-side human presence sensor 10b being configured to transmit a detection signal when it detects a human body, and the parent-side human presence sensor 10a being configured to transmit a detection lighting control signal, which is a control signal for the lighting device 100, when it detects a human body or receives a detection signal directly or indirectly from the child-side human presence sensor 10b.

[0107] With this configuration, the sensing system 2 according to this embodiment has the advantage that only the parent-side motion sensor 10a transmits a control signal for the lighting fixture 100, making it less likely for the lighting system 1 to malfunction, and therefore enabling accurate control of the lighting fixture 100 even when multiple motion sensors 10 are installed. Furthermore, the sensing system 2 does not require a control device such as a gateway other than the parent-side motion sensor 10a and the child-side motion sensor 10b, and therefore has the advantage that the lighting system 1 can be installed easily and at low cost.

[0108] Furthermore, in the sensing system 2 according to this embodiment, each of the multiple motion sensors 10 is configured to be switchable between a master mode in which it functions as a master-side motion sensor 10a and a slave mode in which it functions as a slave-side motion sensor 10b. This configuration eliminates the need for manufacturers to separately manufacture and sell master and slave units, allowing manufacturers to offer the motion sensors at low prices, thereby enabling users to install the lighting system 1 at low cost. For example, if a user wishes to split one lighting system 1 into two lighting systems 1, the slave-side motion sensor 10b, which has been in slave mode, can be switched to master mode and used as the master-side motion sensor 10a. This eliminates the need to purchase a new master unit, making it easy and inexpensive to add more lighting systems 1. Furthermore, the ability to switch between master mode and slave mode allows users to purchase a unit without being aware of whether it is a master unit or a slave unit, thereby preventing the user from accidentally purchasing multiple master units.

[0109] Furthermore, in sensing system 2 according to this embodiment, parent motion sensor 10a includes memory 60 that stores lighting control information 62 for one or more lighting devices 100, and the detection illumination control signal includes lighting control information 62 (detection illumination control information 62a in this embodiment). This configuration allows the brightness, color temperature, and emitted color of lighting device 100 to be set and stored when it is turned on, which has the advantage of allowing users to freely set the lighting brightness, color temperature, and emitted color required for a wide variety of installation locations.

[0110] Furthermore, in sensing system 2 according to this embodiment, master-side motion sensor 10a is configured to transmit an elapsed time illumination control signal, which is a control signal for lighting device 100, when a predetermined time has elapsed since transmitting the detection-time illumination control signal. With this configuration, master-side motion sensor 10a transmits the elapsed time illumination control signal, so that one or more slave-side motion sensors 10b do not need to have time information and do not transmit elapsed time illumination control signals, which has the advantages of reducing power consumption of slave-side motion sensors 10b, reducing network load, and suppressing malfunctions to accurately control lighting device 100.

[0111] Furthermore, in sensing system 2 according to this embodiment, the on-detection illumination control signal is a signal that increases the brightness of lighting device 100, and the elapsed-time illumination control signal is a signal that decreases the brightness of lighting device 100. This configuration temporarily increases the brightness of lighting device 100 when a human body is detected and automatically decreases the brightness after the lighting time has elapsed, which has the advantage of reducing the power consumption of lighting device 100. Furthermore, reducing the time that lighting device 100 remains brightly lit reduces heat generation from lighting unit 120 of lighting device 100, which is expected to extend the life of lighting device 100.

[0112] Furthermore, in sensing system 2 according to this embodiment, the detection illumination control signal is a signal that causes lighting device 100 to light up in a first color, and the elapsed time illumination control signal is a signal that causes lighting device 100 to light up in a second color. This configuration has the advantage of being able to visually warn a user who mistakenly enters a restricted area, to provide a visual illumination effect to welcome visitors, or to provide a crime prevention illumination effect that is expected to deter crime.

[0113] Furthermore, in the lighting system 1 according to this embodiment, the multiple motion sensors 10 and one or more lighting fixtures 100 form a mesh network NW. This configuration has the advantage that the multiple motion sensors 10 and one or more lighting fixtures 100 can be installed anywhere within the range where the mesh network NW can be configured. Furthermore, when the installation range of the lighting system 1 needs to be expanded, the expansion can be easily performed.

[0114] Furthermore, in the lighting system 1 according to this embodiment, at least one of the master side motion sensor 10a, the slave side motion sensor 10b, and the lighting fixture 100 is configured to issue a warning to the user when it detects multiple master side motion sensors 10a on the mesh network NW. This configuration allows the user to immediately and visually notice that multiple master side motion sensors 10a have been mistakenly connected, which has the advantage of making the setting and installation of the lighting system 1 easier.

[0115] Furthermore, lighting system 1 according to this embodiment includes a setting terminal 200 that can set lighting control information 62 for one or more lighting fixtures 100, and master-side motion sensor 10a includes a memory unit 60 that stores lighting control information 62 set by setting terminal 200, and the detection-time lighting control signal includes lighting control information 62 (detection-time lighting control information 62a in this embodiment). Such a configuration has the advantage that the user can set various lighting control information 62 in master-side motion sensor 10a via setting terminal 200.

[0116] [Variations] Although the preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the above-described embodiments. Various modifications and improvements can be made to the above-described embodiments.

[0117] For example, in the above-described embodiment, the multiple human presence sensors 10 are each configured to be switchable between a parent mode in which they function as the parent-side human presence sensor 10a and a child mode in which they function as the child-side human presence sensor 10b. However, this is not limited to this. The multiple human presence sensors 10 do not have to be switchable between the parent mode and the child mode. Furthermore, in this embodiment, the switching between the parent mode and the child mode is performed by the user via the mode selector switch 72. However, this is not limited to this. Among the multiple human presence sensors 10 in the detection standby state, the human presence sensor 10 that first detects a human body may be configured to automatically function as the parent-side human presence sensor 10a, and the other human presence sensors 10 may automatically function as the child-side human presence sensors 10b. With this configuration, the multiple human presence sensors 10 may automatically return to a state before functioning as the parent-side human presence sensor 10a and the child-side human presence sensor 10b after the parent-side human presence sensor 10a transmits the elapsed illumination control signal.

[0118] In the above-described embodiment, master-side motion sensor 10a includes memory 60 that stores lighting control information 62 for one or more lighting fixtures 100, and the detection-time lighting control signal includes lighting control information 62. However, this is not limited to this. Master-side motion sensor 10a may not store lighting control information 62 in memory 60, and instead, one or more lighting fixtures 100 may store lighting control information 62 in memory 180. The detection-time lighting control signal does not need to include lighting control information 62. Furthermore, slave-side motion sensor 10b may store lighting control information 62 in memory 60. Furthermore, while the storage unit 60 is described as storing lighting control information master 64, this is not limited to this, and storage unit 60 does not need to store lighting control information master 64.

[0119] In the above-described embodiment, the parent-side motion sensor 10a is configured to transmit an elapsed illumination control signal, which is a control signal for the lighting device 100, when a predetermined time has elapsed since transmitting the detection illumination control signal. However, this is not limited to this. The parent-side motion sensor 10a does not have to transmit an elapsed illumination control signal. One or more lighting devices 100 may determine that a predetermined time has elapsed and change their illumination state. Furthermore, the elapsed illumination control signal has been described as including illumination control information 62 (elapsed illumination control information 62b in this embodiment), but this is not limited to this and may not include illumination control information 62. For example, the elapsed illumination control signal may simply be a signal indicating that a predetermined time has elapsed, and the lighting device 100 may be configured to return to its original illumination state after receiving the elapsed illumination control signal. Including the elapsed illumination control signal in the illumination control information 62 has the advantage of allowing the user to freely set the brightness and color temperature of the illumination during the detection standby state.

[0120] Furthermore, the base unit-side motion sensor 10a may be equipped with a clock and configured to transmit an elapsed lighting control signal when a predetermined time has passed or when a predetermined time has elapsed since transmitting the detection lighting control signal. With such a configuration, the lighting system 1 can, for example, detect a human body in an office or the like when the first employee arrives at work and turn on the lighting fixture 100, and automatically turn off the lighting fixture 100 after all employees have left work. In addition, in a hospital or an apartment building, the lighting fixture 100 can be automatically turned off at the lights-out time. In a general residence, the lighting fixture 100 can be automatically turned on when a human body is detected when a person returns home and automatically turned off the lighting fixture 100 at bedtime. Furthermore, the base unit-side motion sensor 10a can be configured to transmit an elapsed lighting control signal when it detects locking or reading of an access control card upon leaving the room.

[0121] In the above-described embodiment, the detection illumination control signal is described as a signal that increases the brightness of lighting device 100 or a signal that turns on lighting device 100 in a first color, and the elapsed illumination control signal is described as a signal that decreases the brightness of lighting device 100 or a signal that turns on lighting device 100 in a second color. However, this is not limited to this. The detection illumination control signal may be a signal that increases the brightness of lighting device 100 and turns on lighting device 100 in a first color, and the elapsed illumination control signal may be a signal that decreases the brightness of lighting device 100 and turns on lighting device 100 in a second color. Alternatively, the detection illumination control signal may be a signal that decreases the brightness of lighting device 100, and the elapsed illumination control signal may be a signal that increases the brightness of lighting device 100.

[0122] Furthermore, when lighting control information 62 is stored in memory 180 of lighting device 100, the detection-time lighting control signal and the elapsed-time lighting control signal may simply be signals that cause lighting device 100 to read predetermined lighting control information 62. In other words, the detection-time lighting control signal and the elapsed-time lighting control signal do not have to include lighting control information 62. For example, the detection-time lighting control signal and the elapsed-time lighting control signal may include a registration number (scene number), and lighting control unit 162 of lighting device 100 may read lighting control information 62 linked to the registration number (scene number) from memory 180 and control the light-emitting unit of lighting unit 120. When human presence sensor 10 and lighting device 100 have such a configuration, a setting signal including information set by setting terminal 200 is transmitted to lighting device 100.

[0123] In the above-described embodiment, the plurality of motion sensors 10 and one or more lighting fixtures 100 are described as constituting a mesh network NW, but this is not limiting. The plurality of motion sensors 10 and one or more lighting fixtures 100 can adopt any of various connection configurations (network topologies). For example, the master motion sensor 10a, one slave motion sensor 10b, and one lighting fixture 100 can form a star-shaped network.

[0124] In the above-described embodiment, at least one of the master side motion sensor 10a, the slave side motion sensor 10b, and the lighting fixture 100 is configured to issue a warning to the user when it detects multiple master side motion sensors 10a on the mesh network NW. However, this is not limited to this. The master side motion sensor 10a, the slave side motion sensor 10b, and the lighting fixture 100 do not have to issue a warning to the user when it detects multiple master side motion sensors 10a on the mesh network NW. Alternatively, when multiple master side motion sensors 10a are detected on the mesh network NW, only one master side motion sensor 10a may function in master mode, and the other master side motion sensors 10a may automatically switch to slave mode.

[0125] In the above-described embodiment, the lighting system 1 is described as including the setting terminal 200 capable of setting the lighting control information 62 for one or more lighting fixtures 100, the parent-side motion sensor 10a is described as including the memory unit 60 that stores the lighting control information 62 set by the setting terminal 200, and the detection-time lighting control signal includes the lighting control information 62. However, this is not limiting. The lighting system 1 does not necessarily have to include the setting terminal 200.

[0126] In the above-described embodiment, the control signal transmitter 36 of the master mode controller 30 of the master-side motion sensor 10a is described as transmitting a detection-time illumination control signal and a lapse-time illumination control signal. However, this is not limited to this, and the control signal transmitter 36 may transmit one or more illumination control signals. That is, the master-side motion sensor 10a may control the lighting device 100 not only to switch between two lighting states but also to switch between three or more lighting states. Furthermore, while the above description assumes that the multiple slave-side motion sensors 10b transmit the same detection-time illumination control signal, this is not limited to this. For example, the first slave-side motion sensor 10b may transmit a detection-time illumination control signal A, and the second slave-side motion sensor 10b may transmit a detection-time illumination control signal B. That is, the multiple slave-side motion sensors 10b may be configured so that the master-side motion sensor 10a can identify which slave-side motion sensor 10b has detected a human body from the detection-time illumination control signal.

[0127] For example, after a predetermined lighting time has elapsed, the lighting control signal may be transmitted multiple times so that the light-emitting unit of lighting unit 120 of lighting device 100 gradually becomes dimmer. Furthermore, in the present embodiment, the detection lighting control signal is transmitted again when a human body is detected again or a detection signal is received before the lighting time has elapsed, but this is not limited to this. For example, if a human body is detected twice, the lighting control signal may be transmitted so that the light-emitting unit becomes even brighter than after the first detection lighting control signal was transmitted.

[0128] Also, for example, as shown in Figure 8, when multiple human presence sensors 10 are installed in a one-way corridor or the like, the human presence sensor 10a on the parent unit side may transmit a detection lighting control signal when the human presence sensor 10 on the entrance side detects a human body, and may transmit a passage lighting control signal when the human presence sensor 10 on the exit side detects a human body.

[0129] In the above-described embodiment, the master-side motion sensor 10a is described as transmitting the same detection illumination control signal and elapsed illumination control signal to all lighting fixtures 100 constituting the mesh network NW, but this is not limited to this. The master-side motion sensor 10a may transmit illumination control signals containing different lighting control information 62 to each lighting fixture 100 or to a subset of the lighting fixtures 100.

[0130] In the above-described embodiment, the parent unit side human presence sensor 10a has been described under the assumption that all lighting fixtures 100 are turned on simultaneously, but this is not limited to this, and special lighting control may be performed, such as turning on multiple lighting fixtures 100 sequentially along the user's route.

[0131] In the above-described embodiment, the human presence sensor 10 and the lighting fixture 100 are assumed to be provided separately, but this is not limited thereto, and the human presence sensor 10 and the lighting fixture 100 may be integrated.

[0132] In the above-described embodiment, the human presence sensor 10 has been described as including the indicator 16, but this is not limited thereto, and the human presence sensor 10 may not include the indicator 16. Also, in the above-described embodiment, the human presence sensor 10 has been described as including the notification light source 17, but this is not limited thereto, and the human presence sensor 10 may not include the notification light source 17. Furthermore, in the above-described embodiment, the human presence sensor 10 has been described as including the change-over switch 70, but this is not limited thereto, and the human presence sensor 10 may not include the change-over switch 70.

[0133] In the above-described embodiment, the detection signal transmitter 32 of the master mode control unit 30 of the master side motion sensor 10a and the detection signal transmitter 42 of the slave mode control unit 40 of the slave side motion sensor 10b transmit the detection signal to the motion sensors 10 and lighting devices 100 that make up the mesh network NW, rather than to a specific destination. However, this is not limiting. For example, the detection signal transmitter 32 of the master mode control unit 30 may transmit the detection signal directly or indirectly to one or more slave side motion sensors 10b. Furthermore, the detection signal transmitter 42 of the slave mode control unit 40 may transmit the detection signal directly or indirectly to the master side motion sensor 10a. Similarly, the control signal transmitter 36 of the parent mode controller 30 may transmit a detection time lighting control signal and an elapsed time lighting control signal directly or indirectly to one or more lighting fixtures 100, and the setting terminal 200 may transmit detection time lighting control information 62a and elapsed time lighting control information 62b that have been set directly or indirectly to the parent side human presence sensor 10a.
